Temperature for Cleaning Water Soluble Flux

  • Flux

  • The general trend for water temperature in aqueous cleaning applications is that hotter is better.  Running hotter water in equipment is also generally more expensive.  To allow a good process window, we design most of our water soluble fluxes to be cleaned in room temperature de-ionized water.  With this in mind, you have some “wiggle-room” in your process to turn up the heat if you want to run a longer or hotter than normal reflow (which may char a flux, impacting cleanability).
